阅读理解。     Nuclear energy is a controversial topic. There has been widespread public debate over it. It seems that the
nuclear energy is either a gigantic disaster waiting to happen or the all-powerful way of the future.
     It is often believed that unclear energy is something we cannot do without. We live in a consumer society
with a huge demand for commercial products of all kinds. Besides, an increase in industrial production is
considered to be one solution to the problem of mass unemployment. Such an increase assumes an abundant
and cheap energy supply. Many people believe nuclear energy provides an endless and economical source of
power and that it is therefore fundamental for an industrially developing society. Among other advantages is
that unclear power, except for accidents, is clean. A further advantage is that a nuclear power station can be
run and maintained by relatively few technical and administrative staff. The nuclear reactor represents a great
step in our scientific evolution and, whatever the anti-nuclear group says, it is wrong to expect a return to
more primitive sources of fuel.
     However, opponents (people who oppose something)of nuclear energy point out that nuclear power stations
bring a direct danger not only to the environment but also to civil liberties. Environmentalists argue in the long
run nuclear energy wastes valuable resources and disturbs the ecology to an extent which could bring about
the destruction of the human race. Furthermore, it is questionable whether unclear power is a cheap source
of energy when everything is considered. There have, for example, been very costly accidents in America, in
Britain and, of course, in Russia. The possibility of increases in the cost of uranium (铀) in addition to the cost
of greater safety provisions could price nuclear power out of the market.
     In spite of the case against nuclear energy above, nuclear energy programmes are expanding, which
assumes a continual growth in industrial production and consumer demands. However, it is doubtful whether
this growth will or can continue. Having weighed up the arguments in both sides, it seems that there are good
economic and ecological reasons for sources of energy other than nuclear power. 1. What"s the writer"s attitude toward nuclear energy? A. Objective.
B. Negative.
C. Tolerant.
D. Appreciative. 2. According to the opponents, which of the following is true of nuclear energy? A. Primitive.
B. Endless.
C. Cheap.
D. Unsafe. 3. Some people believe that nuclear energy is the most important because _____.A. nuclear power stations can be run and maintained by relatively few staff
B. it can meet the growing demand of an industrially developing society
C. it represents a huge step forward in our scientific evolution
D. it provides a perfect way out to increase employment 4. Which of the following shows the structure of the passage? A.

阅读理解。     Traditional surgical procedures require surgeons to make large incisions (伤口) in a patient"s body in order
to gain access to the organs inside. It was once common for heart surgeons, who perform highly specialized
and complex procedures, to make long incisions in a patient"s chest and then split the breastbone to reach the
heart. Patients who undergo surgery are often at the risk of infection (感染), as bacteria can infect the cut in
the skin. In addition, there is often a lengthy recovery period.
     A surgical technique known as "keyhole surgery" has become more common in recent years. In general,
the surgeon will make a couple of small incisions around the area where the operation I"m going to be
performed. Tubes are pushed into the holes, and a tiny camera is put into the body. The camera is attached to
a large monitor screen and the doctor can see it while performing the operation. In addition to the camera,
doctors also push their tiny surgical instruments through the tubes. The awkward part of keyhole surgery is
that it is counterintuitive; that is to say, if a surgeon wants to move the tool to the left, he or she must push it
to the right.
     Another new machine called the "da Vinci Surgical System" has been tested in hospitals in the US-Unlike
keyhole surgery, this robot"s moving parts are designed to copy man"s hand and wrist movement, thus
providing better control and sensitivity. Sitting at a console (控制台) a few feet from the patient, the surgeon
can control the instruments by moving highly sensitive pads. The area of the body is enlarged on a screen,
which gives surgeons a view similar to that of a traditional surgical procedure.
     The da Vinci Surgical System has been welcomed as revolutionary by many surgeons. Patients with serious
illnesses must still undergo major surgery, but the smaller incisions typically mean a shorter recovery time. On
the downside, some operations have taken up to fifty minutes longer because surgeons are inexperienced at
using the new technology. As surgeons become more familiar with the machines, the time needed for surgical
procedures is likely to decrease. 1. What can be learned about the traditional surgery according to the passage? A. Long incisions are made in a patient"s chest.
B. It often takes a longer time to do an operation.
C. The cost of the traditional surgery is very high.
D. The incision is likely to be infected after the operation. 2. Which of the following is one disadvantage of keyhole surgery? A. It requires the use of long thin tools and a tiny camera.
B. The doctor cannot view the inside of the patient"s body clearly.
C. The direction in which a doctor moves the surgical tools is opposite.
D. A tiny camera has to be inserted into the patient"s body in advance. 3. The da Vinci Surgical System differs from keyhole surgery in that it _____. A. requires that a surgeon make more small incisions on a patient
B. reduces the amount of time it takes to perform a surgical procedure
C. allows the surgeon to use the surgical instruments more sensitively
D. gets rid of the need for surgeons to make large incisions on patients 4. The passage mainly tells readers about _____. A. the challenges brought about by new technology
B. the application of new technologies in modem surgery
C. the reflections on the development in medical science
D. the benefits and drawbacks of the da Vinci Surgical System

阅读理解。     Have you ever imagined what the world will be like in the near future? A recent study shows that the
world in 2100 will be more crowded, more polluted and less stable ecologically than the world we live in
now. Visible ahead is serious stress involving population, resource and environment. Despite greater food
output, people in the world will be poorer in many ways than they are today.
     For hundreds of millions of the extremely poor, the outlook for food and other necessities of life will
be no better, for many it will be worse.
     While the economies of the developing countries are expected to grow at a faster rate than those of
the industrialized nation, the total national product per head in most less developed countries remains low.
The existing gap between the rich and poor nations will further widen.
     World food production is estimated to increase by 90 percent from 2000 to 2100. Most of that increase
goes to the countries that already have relative higher per-head food consumption. Mean-while, per-head
consumption of food in the developing countries will scarcely improve or will actually fall far below the
present inadequate level. What is worse is that prices for food are expected to double.
    As a result, many less developed countries will have increasing difficulties meeting energy needs. For
the one quarter of mankind that depends primarily on wood for fuel, the outlook is not hopeful.
     Regional water shortage will become more severe. In the 1970-2100 period population growth will
require twice as much water as it does today in nearly half the world. Still greater increases would be needed
to improve standards of living. Development of new water supply will become more costly. 1. According to the passage, in 2100 although output of food will be greater, _____. A. people will have sufficient food supplies
B. the resource will become more than enough
C. in most developing countries people will have less food than they have today
D. the living standards of the world"s population will improve greatly 2. According to the author, in 2100 for many poor people, _____. A. things will get even worse
B. things will be a little better
C. it will be necessary for them to improve their housing
D. it will be impossible to obtain enough necessities of life 3. In the 2000-2100 period, the large proportion of global increase of food production goes _____. A. to 90 percent as estimated
B. to any country in the world that needs it
C. to developing countries
D. to those countries that already have high per-head consumption 4. The passage is mainly concerned about _____. A. the future problems in the world
B. water and air pollution
C. water and food shortages
D. food production and consumption

阅读理解。     You know the drill when it comes to losing weight-take in fewer calories, burn more calories. But you
also know that most diets and quick weight-loss plans have about as much substance as a politician"s campaign
pledges. You"re better off finding several simple things you can do on a daily basis-along with following the
cardinal rules of eating more vegetables and less fat and getting more physical activity. Together, they should
send the scale numbers in the right direction: down.
     1. Treat high-calorie foods as jewels in the crown. Make a spoonful of ice cream the jewel and a bowl
of fruit the crown. Balance a little cheese with a lot of salad.
     2. Eat five or six small meals or snacks a day instead of three large meals. A 1999 South African
study found that when men ate parts of their morning meal at intervals over five hours, they consumed almost
30 percent fewer calories at lunch than when they ate a single breakfast. Other studies show that even if you
eat the same number of calories distributed this way, your body releases less insulin, which keeps blood sugar
steady and helps control hunger.
    3. Walk for 45 minutes a day. The reason we"re suggesting 45 minutes instead of the typical 30 is that a
Duke University study found that while 30 minutes of daily walking is enough to prevent weight gain in most
relatively sedentary (久坐的) people, exercise beyond 30 minutes results in weight and fat loss. Burning an
additional 300 calories a day with three miles of brisk walking (45 minutes should do it) could help you lose 30
pounds in a year without even changing how much you"re eating.
     4. Bring the color blue into your life more often. There"s a good reason you won"t see many fast-food
restaurants decorated in blue; Believe it or not, the color blue functions as an appetite suppressant. So serve up
dinner on blue plates, dress in blue while you eat, and cover your table with a blue tablecloth. Conversely, avoid
red, yellow, and orange in your dining areas. Studies find they encourage eating.
     5. Clean your closet of the "fat" clothes. Once you"ve reached your target weight, throw out or give
away every piece of clothing that doesn"t fit. The idea of having to buy a whole new wardrobe if you gain the
weight back will serve as a strong incentive to maintain your new figure. 1. The passage aims to _____. A. advertise weight-loss products
B. give advice on losing weight
C. persuade you to go on a diet
D. talk you into giving away clothing that doesn"t fit 2. According to the passage, which of the following is true? A. ice cream can be made into the jewel.
B. the color blue encourages eating.
C. many fast-food restaurants are decorated in blue.
D. Eating five or six small meals helps reduce weight. 3. We can infer from the passage that _____. A. cheese is high in calories
B. a big meal helps control hunger
C. a 45-minute walk a day discourages your appetite for food
D. buying new clothes can reduce weight 4. The author agrees _____. A. quick weight-loss plans work well
B. people should cat more fruit to lose weight
C. going on a diet is they only way to lose weight
D. restaurants should serve food with blue plates

阅读理解。     October 15th is Global Handwashing Day. Activities are planned in more than twenty countries to get
millions of people in the developing world to wash their hands with soap.
    Experts say people around the world wash their hands but very few use soap at so-called critical moments.
These include after using the toilet, after cleaning a baby and before touching food.
     Global Handwashing Day is the idea of the Public-private Partnership for handwashing with soap. The
goal, they say, is to create a culture of handwashing with soap. The organizers say all soaps arc equally
effective at removing disease-causing germs (细茵). They say the correct way to wash is to wet your hands
with a small amount of water and cover them with soap. Rub it into all areas, including under the fingernails.
Then, wash well under running water. Finally, dry your hands with a clean cloth.
    The Partnership says soap is important because it increases the time that people spend washing. Soap also
helps to break up the dirt that holds most of the germs. And it usually leaves a pleasant smell, which increases
the chances that people will wash again.
     It also says that washing hands with soap before eating and after using the toilet could save more lives than
any medicine. It could help reduce cases of diarrhea (痢疾), which is the second leading cause of child deaths,
killing more than one and a half million children a year, by almost half. 1. What does the author intend to tell us in the passage? A. To keep healthy by washing hands.
B. To wash hands with soap.
C. To take action to wash hands.
D. To wash hands often.2. Which of the following is the right way to wash hands?
    a. Washing hands well.
    b. Covering hands with soap.
   c. Drying hands.
    d. Rubbing hands with soap.
    e. Wetting hands. A. a-c-b-e-d
B. e-d-a-b-c
C. a-c-b-d-e
D. c-b-d-a-c 3. Which fact can"t explain why soap is important?A. It gives people a longer handwashing lime.
B. It helps to remove a lot of germs from hands.
C. It attracts people to do more handwashing.
D. It gets all people into the habit of washing hands. 4. According to the last paragraph, diarrhea is a disease that ______? A. kills half of the kids in the developing countries a year
B. causes the greatest number of child deaths
C. can be prevented to some degree by washing hands with soap
D. can"t be cured without washing hands

根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。      Recently some American scientists have given a useful piece of advice to people in industrialized
countries. They say people should eat more of the same kind of food eaten by humans living more
than 10,000 years ago. 1_______
     The scientists say that human life has changed greatly. Our bodies have not been able to deal with
these changes in lifestyle and this has led to new kinds of sicknesses. 2_______ They are called "diseases
of civilization". Many cancers and diseases of the blood system arc examples of such diseases.
    The scientists noted that people in both the Old Stone Age and the New Stone Age enjoyed very little
alcohol or tobacco, probably none. 3_______ However, a change in food is one of the main differences
between life in ancient times and that today.
     Stone Age people hunted wild animals for their meat,which had much less fat than domestic (驯养的)
ones. They ate a lot of fresh wild vegetables and fruits. They did not have milk or any other dairy products,
and they made very little use of grains. 4_______ We eat six times more salt than our ancestors and we
eat more sugar as well. We eat twice as much fat but only one third as much protein (蛋白质) and much
less vitamin C.
     5_______ But the scientists say that we would be much healthier if we cat much the same way the
ancient people did, cutting the amount of fat, salty and sweet food. A. Stone Age people lived a simple life without any meat.
B. But today, we enjoy eating a lot of these.
C. In that case, they would live a much healthier life.
D. Ancient people also got lots of physical exercise.
E. These new sicknesses were not known in ancient times.
F. People today probably don"t want to live like our ancestors.
G. Modern people used to suffer from "diseases of civilization".
